2 Guldengroschen - Frederick III

The Ernestinian guldengroschen of this period sits at the origin point of a monetary revolution. Saxony's silver output from the Erzgebirge mines — particularly Annaberg, founded in 1496 — was so abundant that the Albertine and Ernestinian lines were among the first dynasties capable of striking large-denomination silver coins in quantity sufficient for actual commerce. This double guldengroschen, at roughly twice the weight of the already-ambitious single piece, pushed the limits of what late medieval minting infrastructure could consistently produce.

Frederick III's epithet "the Wise" was earned partly through his management of exactly this kind of economic resource. The dies for this series are known to show considerable variation across the striking period, and Keilitz's classification reflects genuine differences in die workmanship rather than purely administrative distinctions.
